Application filed September 20, 19.09. Serial No. 518,641.

To all whom it may concern:

Be it known that I, RAYMOND S. Loan, of Pittsburgh, in the county of Alleghen and State of Pennsylvania, have invente certain new and. useful Improvements in Clamping Devices for Pipe-Joints, of which the followin is a full,-clear,.and exact de scription, re erence being had to the accompanying drawings, specification.

The object of a simple, inexpensive, and efiicient device for sealing or packing pi-pe joints against leakage.

forming part of this The invention will be found particularly adatable to the sealing of the ordinary lead pac ed socket joint of the cast pipe type.

I will now describe, in connection w1th the accompanying drawings, my invention so that others skilled in the art to which it appertains may understand and construct the same. 1

Figure 1 is a longitudinal sectional view showing my invention as applied to the sealing of the joint of the meeting ends of two pipe sections of the cast type; Fig. 2 is a transverse sectional view taken on the line. II-II' of Fig. 1; and Fig. 3 is a longitudinal sectional view showing my invention as applied to a joint employing a coupling ring or sleeve. y

In the drawings, the reference numeral 2 indicates the socketed or bell end of a pipe section of the ordinary cast type, which is adapted to receive the spigotend of the connecting pipe section 3; the joint being packed in the usual manner by means of lead or other packing material interposed between the opposin walls-of the two pipe members as indicate abutment with the end face 5 of the socketed pipe member 2 is the concentrically disposed ring member 6 which ma be secured to the member 2 by means of the nuts carried "by the stud bolts 7 This ri member is provided with an inner ann ar wall or face 8 between which and the outer wall of the pipe member 3 is adapted to be received the packing ring or gasket 9 which may be of any sultable material and which may partially ous to the joint to be sealed, as shown in Fig. 1. vAt this point where the packing rin 9 abuts against the end face 5, the inner ace of the ring member 6 slightly curves away my invention is to provide by the numeral 4, In.

abut against the end face 5 cont1gu from the face 5. Between this curved portion of the ringand face 5 the packing ring 9 may beiclamped by the ring 6 through the action of the tightening nuts 6', thereby sealing the joint at this contiguous int of ring 6 and face 5. Alsoca'rried by the studs 7 is the follower or clamping ring 10 which is provided with. the annular projecting flange 11 which is adapted to abut against the packing ring 9 and by means of which, when the follower is caused to be moved toward the face 5 or forced home by means of the tightening nuts 12, the ask ng ring will be caused to be compressed? By means of the packing retaining ring 6 spreading of the packing ring laterally or on radial lines is prevented, insuring an effectual sealing of the joint when packing is caused. to be compressed by the drawing-home of the follower ring 10 in the manner above described. The .ring member 6 and the follower 10 may be segmentally divided as inap lication to the i is will be seen inP Fig. 3, my improved form of clamping device is readily applicable to the packing of a joint employing a coupling ring or sleeve. In this Fig. 3 the numerals 2 and 3' indicate the meeting ends of the pipe sections, while the numeral 4 indicates the surrounding coupling sleeve or ring. This coupling ring 4' is provided with the end faces 5 corresponding with the end face 5 of the socketed pipe member described above. The ring members 6, gas-.

kets 9, and clam-ping rings 10' correspond, respectively, with the ring 6, gasket 9, and clamping rmg 10 above described,

i'Means for drawing together or forcing home the follower rings 10 for a seating of dicated by the letter a for convenience in the gaskets 9 comprise the bolts 13 which extend from one follower ring to the other across the coupling rin 4 .and are provided with the tightening nuts 14. The ring members 6' may beheld against displacement or creeping by having the follower rings 10' brought in abutment therewith when the latter rin s are forced home or drawn toward each ot er. I

The device is simple in construction, being such that the gasket retaining ring member and the follower may be readily cast, formed from sheet metal, or made from rolled shapes. A packing ring of any suitable material may be employed.

,the combination of I do not here claim the construction set forth in Fig. 3 of the drawings as thesame is claimed in a separate application filed by me, Serial No. 588,458, and which is a division of the subject matter of this application.

It will, of course, be apparent that many changes ma be made in the construction set forth w ich would not be a departure from my invention and I do not, therefore, desire to limit myself thereto.

The advantages of my invention will be readily appreciated by those skilled in the art.

The device is simple, strong, and inexpensive and-is effectual in operation.

Havin thus described my invention, what I c aim and desire to secure by Letters Patent is 1. In a device of the character described, the combination of two cooperating pipe ends comprising bell and spigot members of a main packing between the walls of the members, a ring member contiguous to the end face of the bell end and provided with an annular face disposed oppositely to the outer wall of the spigot member, a packing ring interposed between the oppositely disposed wall of the ring member and pipe section, and means for forcing the packing ring home between the two opposing walls.

2. In a device of two cooperating pipe ends comprising bell and spigot members of a main packing between the walls of the members, a ring member-secured to the bell end -pi e member and provided with an annular ace disposed oppositely to the outer "posed wall of the ring mem section, and means for forcing the pac ter pipe member,

wall of the spigot pipe member, a packing ring interposed betweenthe 0 er. andipe g ring home between the two opposing walls. 3. In a device of the character described, the combination of two cooperatin ends comprising bell and spigot mem ers of a main packing between the walls of the members, a nin member in abutment with the end face 0 the first named pi emem ber and provided with an outwar 1 projecting annular flange surrounding t e lata packing ring interposed between the annularflange of the ring member and the wall of the pi e member, and means for forcing the packing ring home between the opposin flangeand pipe wall. 4.'
